MAKE is celebrating its just-released Ultimate Guide to 3D printing with an international maker meetup tonight at 6pm PT and you’re invited.

Mike Senese, executive editor of MAKE and Anna Kazunias France, MAKE digital fabrication editor, will co-host a live Google+ hangout on air with guests from the seven top performing 3D printer manufacturers. We’ll present a tour of the lab with printers churning out 3D objects and we’ll check in with some of the 3D printing experts who tested machines for our special issue. These experts will talk about the results of our shootout of 23 3D printers and digital fabrication in general.

But that’s not all. You can enter to win a PrintrBot Simple, one of the top performing printers featured in the current issue. Enter here to win. The winner will be announced during tonight’s meetup. See you there.
